CONCRETE-WALL-MOLDING DEVICE.

To all whom it may concern:

Be it known that I, RICHARD TV. FULLER, a citizen of the United States,and a resident of the county of Woodward and State of Oklahoma, havemade certain new and useful Improvements in Concrete VValllitloldingDevices, of which the following is a specification.

My invention relates to improvements in means for making concrete wallsand it consists in the constructions, combinations and arrangementsherein described and claimed.

An object of my invention is to provide a device comprising movable sidemembers forming parts of a mold, said side members being so arrangedthat they may be securely fastened together when the form is beingmolded, and can be removed laterally from the wall when it is desired toremove the mold.

A further object of my invention is to provide means for making eithersingle or double air spaces in the walls.

A further object of my invention is to provide means for strengtheningthe wall sections.

A further object of my invention is to provide means by which the molds,together with the cores for forming the air spaces, may be raised as thewall is being built.

A further object of my invention is to provide means for hoisting anddistributing concrete or cement to various parts of the building underconstruction.

A further object of my invention is to provide a novel form of scaffoldfor use in erecting concrete buildings.

Other objects and advantages will appear in the following specificationand the novel features of the device will be particularly pointed out inthe appended claims.

My invention is illustrated in the accompanying drawings forming part ofthis application in which similar reference characters indicate likeparts in the several views and in which Figure 1 is a plan view of themolds as set up in position for forming the walls of a building. Fig. 2is a section along the line 22 of Fig. 1. Fig. 3 is a transverse sectionthrough the collapsible chimney core. Fig. 3 is a vertical sectionthrough the chimney core. Fig. 4 is a perspective view showing the meansfor attaching the side members of the mold. Fig. 5 is a planSpecification of Letters Patent.

of Fig. 13 looking in the direction of the arrow.

In carrying out my invent-ion I make use of the molding devices bestshown in Fig. 1. These comprise oppositely disposed molding membershaving a relative movement toward and away from each other. Thesemembers may be of greater or less extent. llt will be understood thatthey are intended preferably to form means by which sections of acomplete wall of a room may be formed and are not intended for merelymolding in dividual blocks. A description, therefore, of

the means for forming the wall will be suf-- ficient since obviously theremaining walls are formed 1n precisely the same manner.

Referring now particularly to Figs. 1 and 4 it will be seen that Iprovide oppositely disposed molding members 1 and 2. Fig. 4.

shows that the member 1 is provided on its inner face with markingdevices 3 to inclicate blocks. These may be recessed to represent mortarin the finished block, or may be projections to leave a recess in thefinished block, in which different colored mortar may be applied afterthe wall is finished. The molding members 1 and 2 are provided withupper and lower strengthening flanges 1 and 2 and 1 and 2 respectively.The member 1 has near its ends upwardly extending arms 1 which aredesigned to register with similar arms 2 on the member 2. These arms arepivotally connected together in the yoked ends of a spacing bar 4 bymeans of the pins 5 and 6. At the top of the arm 2 is pivoted a. secondspacing bar 7, having an opening 7 at its end arranged to receive theupper end of the arm 1. The lower spacing member 4 is provided withrecesses 4? on one edge, and a central recess 4 on the opposite edge. Inorder to hold the molding members 1 and 2 together while the wall isbeing made, I provide crank bolts 8 which extend through one member andare threaded in lugs on the other.

The molding members 1 and 2 as described are connected at the corners inthe manner shown in Fig. 1. Referring now to the upper lefth'and cornerit .will be seen that the outer member 1 is connected to a similarmember 1 at right angles to it, by means of the staple9 and the hook andpin connection 10. The inner molding .member 2 is connected with themolding member 2 at right angles to it, by means of the staple 11.Between the ends of the inner molding members or at the corners thereofis a removable spacing member 12, whose purpose will be more clearlyexplained hereinafter. By reference to Fig. 4 it will be seen that Ihave provided the dowel pins 13 in the member 1, which enter the similarmember 1 at right angles to it.

The provision for forming the chimney core is shown in Figs. 1 and 8.These consist of a hollow core formed of the sides 14 which are hingedtogether at 15 in such a manner that the core may be spread out as shownin Fig. 1 to form a regular molding member. The bottom part of the corehas inwardly turned flanges (similar to the one shown at 16) on itsedges to support a wooden block 17. To keep the core in extendedposition, the upper edge of the core is provided with outwardly turnedflanges 18. A spreading block 19 fits into the core and may be held inposition by means of a pivoted locking member 20 which may be turned soas to have its corners project over the flanges 18 to keep the spreadingmember 19 in position, as clearly shown in Fig. 1. The core thus formedis held in position by means of the staples 21 which are secured to theadjacent mold sections.

In order to provide air spaces in the walls, I make use of the coreblocks which are best shown in Figs. 2, 5, 6, 7 and 8. Referring nowparticularly to Fig. 7 I have shown therein a core block 22, providedwith a loop 23 at its upper end for securing it to a suspension bar 24,see Fig. 8. These cores, it will be seen, taper from their upper totheir lower ends. The core block 25 in Fig. 8 is split for the purposeof straddling the spacer bar 4. In Figs. 5 and 6 I have shown a seriesofblocks 22 suspended from a common bar 24. These core blocks may be usedto provide singleair spaces such as shown in Fig. 5 or double air spacessuch as shown in Fig. 8 In the latter case the air spaces 100 arepreferably staggered with the airspaces 200, or in other words the airspaces of one overlap the air spaces of the other.

From the foregoing description of the various parts of the moldingdevice the operation thereof may be readily understood. In beginning thefoundation of the building the parts are set up as illustrated in Fig.l. The cement or concrete is placed in the space 27 between the moldingmembers and around the chimney core and is tamped down solidly. In orderto prevent the spreading of the bottom portions of the molding members 1and 2, I provide the spacing bar 7 with a cam surface 7", which engagesa similar cam surface 1 on the arm 1. As the spacing bar 7 is pusheddownwardly, this forces the upper ends of the arms 1 and 2 slightlyapart, thereby bringing the members 1 and 2 closer together and holdingthem securely in place. Before the concrete has set, the crank bolts 8are removed. Now when the concrete has set, the staples 9 and 11 areremoved and the hook 1O thrown back. The corner wedges 12 are thenremoved, the spacing bar 7 is then I thrown upwardly into the positionshown in Fig. 2. The sides 1 and 2 may be swung apart on their pivots 5and 6 respectively. It will be noted that the provision of the removablewedges 12 at the ends of the molds permits the inner wall 2 to have amovement away from the outer wall. As the outer wall is swung away, thedowel pins 13 are disengaged from the corresponding member 1 at rightangles thereto. The mold sect-ions l and 2 may now be lifted by means ofa spring grapple such as that shown in Fig. 10, at 28 whose ends arehooked in the screw-eyes 5 and 6 respectively. The upper end of thecable is secured by means of the rope 29 which passes over a pulley 56(see Fig. 12), and then downwardly through the eye 30 of the cable. Thisis for the purpose of steadying the same and moving the mold as desired.

I have spoken thus far of the means of forming the foundation wall. Nowwhen it is desired to complete the building, the core blocks are used.In Fig. 4 I have shown the spacing member 4 as provided with recesses 4for two rows of core blocks, and a recess '4 for one row of core blockswhen the spacing member 4 is reversed. In Fig. 2 I have shown two rowsof core blocks in position. These core blocks are suspended upon thespacing members 4, the split core block 25 straddling the spacing memberand the upper part of the block fitting into the recesses 4 In buildingthe wall, the molds are set in position in a similar manner to thatalready described, care being taken to set the crank bolt 8 to preventthe spreading of the molds at the center. After the concrete is filledin, the core blocks are removed by attaching the hooks or cables to thescreweyes 26 and lifting them vertically. I find it expedient sometimesto place a board on the top of the wall on each side of the core blockwith its edges in engagement therewith. Now by standing on the board theconcrete which might adhere to the core block is prevented from comingout with it, thereby leaving a smooth air space. hen it is desired tohave only a single air space the member 4 is reversed as stated and therecess 4 is used for the single row of core blocks. The remainingsections of the wall may be completed in the manner described.

In Figs. 5 and 6 I have indicated the manner of making windows or doorswhich may be done in two ways, either in inserting a frame 31 having atongue 31 and filling in with concrete up to the frame and around thetongue, or inserting a strip corresponding to the tongue 31 with aremovable backing to retain the cement in place of the frame 31 so thatwhen the wall is finished the strip.30, corresponding to 31 may beretained in the wall to which the door or window frame may be secured.

In order to further strengthen the build ing I may use rods 32 like thatshown in Fig. 9. These rods are hooked into or affixed to the frames 31as shown.

The conveyor system which is best adapt ed for use with the moldingapparatus is illustrated in Figs. 11 and 12. In Fig. 11.

I have shown the uprights 35 and 36 which, of course, are preferablybraced in any suitable manner and are provided with the carrying cablesor wires 37 and 38. The former also serves as a brace for the device. InFig. 12 I have shown therein a support 35 similar to the support 35 andthere is a support corresponding to the support 36.

Upon the wire 37 is a double pulley 39, while the wire 38 bears a doublepulley 40. The pulley 39 is limited in its downward movement by a cord41 but may be moved toward the frame. A similar pulley 42 is fastened tothe corner of the framework. The concrete bucket is shown at 43. To thepole 44 is attached the operating ropes or wires 45, 46 and 47. The rope45 passes through the lower roller of the double pulley 39. The rope 46passes through the pulley 42 and the rope 47 passes through the lowerroller of pulley 40. The mixing box is shown at 48. It will be apparentthat when it is desired to convey concrete the bucket 4-3 may be loweredby slackening up on the ropes. After it is filled it may be raisedvertically by pulling on the ropes 46 or 47, it being understood thatthe rope 45 is either held or secured to a stake during the verticalmovement of the bucket. When the bucket reaches the pulley 39 the rope45 is slackened up while the rope 47 is pulled. The bucket thereforewill pass from the pulley 39 underneath the cross pieces 49 and ontoward the pulley On further pulling of the rope 47 in the directionindicated in the figure, the pulley 40 may be moved along the wire 38 toany part of the wall, the rope being slackened in the meantime. Now byslackening the rope 47 the bucket may be made to descend to any placewhere it is to be used, and the load may be dumped by operating theslide 43 in the bottom of the bucket, after which the bucket may bebrought up to its original position by reversing the operation.

In practice I prefer to have two such devices as illustrated in Fig. 11with a cable extending at right angles to the cable 38 toward theinterior of the building. This cable is also provided with a pulleysimilar to that shown at 40 over which another operating wire or ropemay play. It will therefore be apparent, that as soon as the pulley 40reaches the end of its travel, the weight of the bucket may be shiftedon to the pulley running on the cable at right angles, so that thecharge may be traversed along the partition wall to a chimney or anyother place on the interior partition. The bucket may also likewise bemanipulated so as to pass to the outer wall by means of the rope 46. Itwill thus be seen that I have provided a conveying device in which thebucket may be brought from the mixing box, placed at any convenientposition, be carried up over the wall and lowered as desired.

The form of scafiold which I prefer to use in this operation is thatshown in Figs. 13 and 14. This consists of the main supporting board 50having the side flanges 51 and 52 between which is pivotally mounted thedrum 53. A cable 54 is wound around the drum, passes over the roller 55,up through the member 1, over a suspending pulley on the scaffold, suchas those shown at 56 in Fig. 12,'and is secured to the cross member 59on the scaffold. The rope 58 is wound on the other half of the drum andpasses over a roller 59 around the pulley 56 and is secured to the crossmember 60. A ratchet 61 is secured on the shaft of the drum 53 and isprovided with a pivoted locking lever 62, having a pivotal connection 63with a second lever 64. The ends of these levers are immediately beneathopenings 65 in the board 50. In the center of the board 50 is a slot 50through which are adapted to project the sliding handles or spokes 66which project through the wall 67 forming an enlargement of the drum 53and are weighted so as to drop below the upper surface of the scaffoldwhen not in use. A lever 67 is adapted to be moved over the end of theslot so as to be in the path of the handles 66. This description of theparts of the scaffold will be sufficient for a clear explanation of theoperation thereof.

It will be seen that the normal position &

ofthe scaffold is that shown in Fig. 14., in which the weight of thelevers 62 and 64: is suflicient to prevent the ratchet 61 from turning.This will hold the scaffold in position. Now if it is desired to movethe scaffold the screw-eyes 68 are inserted in their respective openingsand screwed to their respective levers 62 and 64. Now by pressing oneither of these screw-eyes with the foot the levers will be releasedfrom the ratchet, allowing the latter toturn easily.

Before this is done, however, one of the ban dles 6G is pulled upwardlyby the operator. The handle is grasped as it comes through the slot 5O"so that whenthe ratchet is released the' scaffold is under the controlof the operator. The handle is now moved either to raise or lower thedevice and as it moves another handle comes up through the slot and isgrasped-by the other operator, there being generally two men on thescafiold. After moving the scaffold up or down to the desired place, thehandles are permitted to drop by gravity beneath the board, the lockinglevers being in the meantime released so as to hold the scaffoldsecurely. As a further precaution, in case the ratchet mechanism shouldnot work well, I provide the lever 67 which may be moved in the path ofthe handle so as to prevent the latter from turning. I use screw-eyesbecause if only one operator is on the scaffold he may insert the end ofa rod in the eye and use the whole rod as a treadle for forcing upon thescrew-eye to release the'ratchet mechanism.
